Optional Modifiers

As each image is processed by the data analysis, modifier strings are appended to the basic file name to distinguish each stage in the process while still conveying the file's origin in a particular image. These modifiers are summarized in Table A.2, and the details are explained in the description of the analysis software in Chapter 8.
